No, weirs WERE needed and this change took time, once the weirs were placed in, the damage had already began.


Again, its not an overnight process, its slow, but not really in geological terms, a hundred years is the blink of an eye in geological terms. You are answering your own questions. The land begins to erode due to wave action, saltwater intrusion kills the vegetation that holds the land together, the land becomes mud, the erosion washes away the mud into the ship channel, gets dredged, repeat. When man interferes with hydrology, the water body tries to correct itself. Look at any pass out into the gulf, one side of the jetties will be shallow and the other side will be highly eroded, and you just keep adding rocks to reduce the problem but the problem will always be there. Rocks and dredging are a temporary fix to a permanent problem
